Bobbin for automatic inflator

Abstract

An automatic inflator comprising a body for receiving a dissolvable pill, said dissolvable pill including an upper surface and a lower surface, at least one of said surfaces including an undulating configuration.

1. An automatic inflator for inflating an inflatable article when the automatic inflator is submersed in a body of water, comprising a body and a dissolvable pill, said body including an actuator coupled to said pill that actuates upon dissolving of said pill to cause inflation of the inflatable article, said dissolvable pill including an upper surface and a lower surface transverse to an axis of said dissolvable pill, at least one of said surfaces including multiple undulating configurations including peaks and troughs oriented such that an imaginary plane extending through said peaks and an imaginary plane extending through said troughs extend parallel to a plane of at least one of said surfaces and transverse to said axis of said dissolvable pill, wherein both said surfaces include said undulating configurations; wherein said undulating configurations are aligned to be out of phase with each other, said undulating configurations providing sufficient strength to preclude actuation of the actuator until said undulating configuration dissolves upon becoming wetted when the inflator is submerged into the body of water. 
   
   
     2. The automatic inflator as set forth in  claim 1 , wherein said undulations extend radially. 
   
   
     3. The automatic inflator as set forth in  claim 1 , wherein said dissolvable pill comprises an annular pill with a center hole.
